Does Your New Exhaust Rattle?
 

Hey guys,

So I just recently installed my Borla S-type exhaust on my mustang. However, I have noticed that in the mornings when starting it up, it has a slight rattle.

I have heard from some members that they drained water from the exhaust by drilling a hole in them?

We did recently have a rainstorm about a week ago and just wondered if that could be the reason for the rattle.

Does anyone know how we can check to be sure.

I don't want to start drilling holes in my exhaust if I don't need to.

Thanks again and let us know if you had a similar problem with your exhaust.

The water is from condensation not rain. If you are starting it in your garage start checking stuff in your garage for a rattle. I thought my car was doing the same but it was something in the garage making the noise.

No rattles here. Exhaust has been on over a year now.

I don't believe the actual vehicle rattles but, the sound is making stuff on the wall rattle. Especially within the first 30-45 seconds before the idle drops below 1k.

I had some FRPP Sports (made by Borla) that had a rattle at low RPMs. It turned out to be a loose weld on a baffle. I called Borla and even without hard evidence they sent me a replacement muffler free. So I would suggest looking over the fittings and hangers to make sure there isn't any rubbing/contact with metal, if not, then give Borla Warranty a call and they should help you out there.

I currently run the S-Types on mine for a year come February and have no issues. Just wished Borla ran a better looking exhaust tip like Corsa.

My car is about as low as it'll get in the back without the exhaust system SITTING on the rear end. When I first installed it it rattled like crazy. I just installed a new hanger and secured it in place, now it's fine. I'm surprised more people haven't had that same issue with the rear end.

No.

No rattles on my Roush ABs nor from the Gt500 ABs I had for a few months.

I had a slight rattle / kinda still do. Seems to show its face when the exhaust is cold. Once it warms up it goes away. I also have Borla S-type and I HIGHLY suggest drilling weep holes in the mufflers. I drained about 2 solo cups worth of water from my mufflers.
